natta225 [31]

Answer:

Option d is correct.

The number of students that chose Target as their favorite store over Ross = 4 students.

Step-by-step explanation:

The graph of the question is obtained from another brainly question on here. But uploading it will lead to deletion of this answer as it would be violating the community guidelines here.

So, I'm going to describe the graph.

The graph provided with the question is a pie chart, with each region clearly shown and the corresponding percentage for each of the students' favourite stores that come up in the survey given as

TJMax - 20%

Wal-Mart - 25%

Ross - 20%

Target - 25%

Others - 10%.

How many more students surveyed chose Target as their favorite store over Ross?

Total number of students sampled = 80

Number of students that picked Target

= 25% × 80 = 20 students

Number of students that picked Ross

= 20% × 80 = 16 students.

Number of students that chose Target as their favorite store over Ross = 20 - 16 = 4 students.

Hope this Helps!!!
